IPC: D02G1/02
Filed: 1960-08-12
Abstract: 908,514. Finishing yarns. SCRAGG & SONS Ltd., ERNEST. Aug. 10, 1961 [Aug. 12, 1960], No. 28003/60 Class 120 (3). Cellulose triacetate yarn is crimped by passing it through forwarding rollers rotating at a constant peripheral speed, heating and then cooling it, passing it through a false-twisting device and then between delivery rollers the peripheral speed of which is 2-6% greater than that of the forwarding rollers and finally collecting the yarn on a rotating package at a speed 5-10% less than that of the delivery rollers. The wound yarn may be subjected to the action of steam at 1-2 atmospheres to stabilize the crimp ; alternatively, the yarn may be subjected to the action of water or water vapour, e.g. at 90‹ C., under conditions of zero or minimum tension for 1-10 minutes, stretched to 80-90% of its original uncrimped length, and subsequently dried. Yarns of opposite remanent torque may be doubled, with or without both yarns having been treated with steam.

Title: Improved method for superheating and decomposing of steam for water gas production
IPC: C10J3/80
Filed: 1930-09-22
Abstract: 363,715. Water gas generation. RUDE, J., 9, Rue Picot, Paris. Sept. 22, 1930, No. 28344. [Class 55 (i).] Steam is superheated and decomposed in a heat regenerator a, heated intermittently by "blow" gases from a producer g, the hot steam then being brought into contact with fuel in a chamber c interposed between the regenerator a and the producer. The gases from the fuel chamber c are passed through a second regenerator b, for adjusting their temperature and to preheat the air for the combustion of the blast gases in the succeeding " blow," before passing through the producer g for improving the quality of the gas. The " blow " gases and preheated air from the regenerator b are burnt in the combustion chamber d, the combustion products proceeding through the fuel bed c before passing to the regenerator a. Further secondary air may be introduced at q; liquid fuel may be injected at t. In modifications, pulverized fuel is blown into the chamber c by means of steam or compressed gas, the fuel being introduced either at the base or at the top of chamber c.

Title: Method and apparatus for telegraph transmission at high speed
IPC: H04L27/10
Filed: 1956-09-18
Abstract: 822,624. Signal transmission systems. NATALI, D. Sept. 18, 1956 [Sept. 19, 1955], No. 28479/56. Drawings to Specification. Class 40 (4). Alternating current telegraph signals from a channel of limited band width are recorded at one speed x and reproduced at an increased speed kx, thereby increasing the band width to that of the transmission link to be used, the reproduced signals then being frequencyshifted to place them in the frequency range of said link. Since the link is now used for only 1/kth of the duration of the original signal, the remainder of the duration may be used for the transmission of signals from further channels. As described, frequency modulated telegraph signals each occupying a band FmŒd# are recorded on magnetic tapes at speed x. These signals are then reproduced in turn at speed kn to produce a signal occupying a band k(FmŒd#). The signal then modulates a carrier Fo=kFmŒFc (where Fc is the centre frequency of the transmission link) and the lower sideband occupying a band width FcŒkdf is transmitted over the link. At the receiving end the signals are applied to a demodulator fed with frequency F0 and the lower side-band taken to produce a signal occupying the band k(FmŒdf) which is recorded at speed kx1. The recordings are then divided amongst a plurality of reproducers running at speed x1 to reproduce the original signals occupying the band FmŒdf.

Abstract: 639,426. Road-making and like apparatus. BEDIN, J. M. J. Oct. 25, 1947, No. 28564. Convention date, June 3, 1946. [Class 107) A machine for use in the preparation of fourdations for load-carrying surfaces partially inserts matrices 16 into the top soil by one or more articulated polygons 17, 18 whose configuration is determined by the shortening of a diagonal strut 20, 20a connected to eccentrics 21, 21a. The matrix is then subjected to repeated blows by a hammer 10 secured to the lower leaf 5 of a bow-spring, the other leaf 6 being secured to the chassis 1 of the machine so that, on the hammer being raised, the spring is tensioned. Two rotating nuts 12 having four symmetrical projections 14 thereon act on two abutments 13 on the hammer guides 11 to raise the hammer. Presser means, such as a spring-loaded jointed boss 24, 25a or a heavy roller, maintain the matrices immediately behind the hammer under pressure whilst the matrices are carried from the rear to the front of the machine by a pivoted swing-bar 27 operated by a pinion 26 and toothed sector 25. The machine is advanced by crutches 32 that engage a matrix that has been driven into the ground, the crutches being carried on a slide controlled by a rack and pinion. The Specification as open to inspection under Sect. 91 describes the use of a matrix in the form of a stake. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to golf-games or golf-practising devices
IPC: A63B69/00
Filed: 1920-10-09
Abstract: 173,879. Billing, N. Pemberton-. Oct. 9, 1920. Golf-practising appliances.-Relates to a golf stroke-indicator of the type in which an arm to which the ball is tethered is mounted so as to swing about two axes at right-angles to one another to indicate the elevation and lateral deviation of the ball and in which a yielding- device to which the ball is connected indicates the length of the stroke, and consists in forming the yielding-device of a sliding-member upon which the arm is mounted so as to be bodily movable therewith. As shown, the indicator comprises a slotted tube 2, Fig. 1, secured to the ground and having tubes 4 containing spring pistons 6 at its ends, and a sliding member 8 mounted so as to slide within the tube and indicate the length of the stroke. The bifurcated arm 14 to which the ball is tethered is pivoted to the quadrant 9 which is pivotally mounted upon the sliding-member so as to move over a scale 19 secured to it. The frictional resistanceof the pivots is sufficient to retain the arm and quadrant in the positions to which they are moved when the ball is played. In use, the slide is moved to the right hand end of the tube and the ball played in the direction of the length oi the tube. The length of the stroke is read upon one or three scales marked upon the tube corresponding to the number of rebounds of the sliding-member 8 from the spring pistons 6, and the elevation and deviation are indicated by the quadrant 9 and scale 19 respectively. Sleeves 21 mounted upon the ends of the tube and actuated by the pistons 6 indicate whether any rebounds have taken place. In a modification, the slide is formed of a short tube weighted with shot. In another arrangement, the slide is screwed upon a spindle 30, Fig. 3 and formed with an extension 31 which engages with guides 32 in the base. One end of the spindle is fixed and the other is secured to the free end of a coiled spring which is mounted within a drum 34. In this case, the length of the stroke is read upon a scale marked on the guides. Alternatively, the length may be indicated upon a scale 38 by a pointer 37 which is actuated through gearing from the spindle. In a further modification, sliding indexes may be provided on the quadrant and scale to indicate the movements of the arm. To play a game, a chart is provided having a course marked upon it, the player marking his strokes upon the chart by use of a protractor or the like. When a green is reached upon the chart, the hole can be played out upon a lawn.

Abstract: 1391349 Labelling machine HEINRICH HERMANN 20 June 1972 [25 June 1971] 28703/72 Heading B8F Articles 1, such as envelopes, are fed in direction 10 on to a continuously moving conveyer 12, and labels 2 are fed in a perpendicular direction 24 on a conveyer 23 to a waiting position between bearer bars 17 and downholder bars 27 before being applied by movement in a mutually perpendicular direction to an article by a roller 19 mounted on a lever arm 20. The roller is released by a solenoid 21, when the leading edge of an article actuates switch 29, and pushes the leading edge 30 of the label into contact with the article, the forward feed of which withdraws the label. For ease of withdrawal the bearer bars 17 may have rotatable sleeves or be rotatably mounted in beam 18. The label feed is controlled conventionally by a label detector. The position of the label may be altered by sliding the beam 18 and label feed means on rails 22. Rollers 14 hold the articles on the conveyer 12, and to accommodate different article heights it is supported by tension springs and mounted on a parallelogram linkage so that it may be lowered.
